PURIFIER/ FOB LIQUID FUELS.

Application filed September 2, 1922. Serial 110,585,954.

To all whom it may concern:

Be it known that l, BRUNO ADLER, a citizen of the German Republic, residing at Dresden, Germany, have invented certain new and useful Improvements in Purifiers for Liquid Fuels, of which the following is a specification.

This invention relates tothe improvement of purifiers and filters for the liquid drivlo ing fuels for internal combustion engines.

It consists in that the liquid fuel is forced by the eccentrical arrangement of the feed pipe with regard to the center of the purifier,

to flow tangentially to the strainer so that a rotating movement is imparted to this fuel. The impurities contained in most liquid fuels are thus thrown against the inner wall of the purifier body and sink upon the bottom in spiral shaped movement, to be tapped off from time to time by means of a purging cock.

The rotating movement of the liquid fuel produces further the automatic cleaning of the filtering surface.

The strainer is further divided into an upper and lower part by a soldered intermediary ring resting upon a shoulder of the body of the purifier. As the strainer is securely closed at the top and bottom ends by two disks and the inlet of the casing is arranged on one side, the outlet on the other side of the intermedial ring the liquid fuel rising in the strainer must traverse also the upper part of the strainer before it can get to the outflow tube, the fuel being thus purified again. l/Vith one strainer a double purifying action is thus produced.

The upper and lower end disks have each an easily removable insertion so that the strainer can be cleaned from the inside also.

In order to facilitate the withdrawal of the strainer a handle consisting of a blade spring is arranged upon the upper end disk or upon the insertion of the same which pro- 3 trudes over the rim of the purifier body after the lid has been screwed off.

A spring is used as handle in order to ensure that the lid in being screwed in compresses the spring so that the intermediary ring of the strainer which tightly fits into the body of the purifier is securely pressed upon the shoulder.

In order that the invention may be clearly understood, Ishall hereinafter proceed to describe the same with reference to the form of construction shown byway of example on the accompanying drawing, wherein:

Fig. 1 is a cross section, and

Fig. 2 a plan view of the purifier, the lid being removed.

The body a of the purifier has an eccentrically arranged inlet tube 7), which in the form of construction shown has a cock 0. The strainer is divided into the lower part 6, closed at the bottom by a disk f, and into the upper part 9. The top disk h which closes the upper strainer part 9 has an insertion 2' upon which a bow-shaped spring is is fixed. The liquid fuel has to traverse this upper part in order to get to the out-- flow tube Z. The lid m closes the body a and, if screwed on, presses with its exten sion a upon the bow-shaped spring 70 so that the intermediary ring (Z which fits tightly into the part of the body a which is situated in proximity of the shoulder 0 is strongly pressed upon this shoulder so that the impurities collected in the lower part of the casing are prevented from getting above the shoulder 0.

The form of construction shown by way of example may be modified in various manners. The spring is instead of being bowshaped can have any other convenient form andthe, insertion 2' could for instance be arranged in the bottom disk instead of in the top disk.

I claim 1. A purifier for liquid fuels comprising a casing having an inlet and an outlet, an internal projecting shoulder upon the inner surface of said casing, a hollow strainer of the form of a rotary body in said casing and closed on both ends, an intermediary ring upon said strainer tightly fitting into said shoulder and dividingthestrainer into a lower and upper part, the inlet of the casing being arranged on one side of the said intermediary ring and eccentrically to the strainer in a manner that the entering liquid flows tangentially to the strainer, the outlet of the casing being arranged on the other side of the said intermediary ring.

2. A purifier for liquid fuels comprising a casing having an inlet and an outlet, an internal projecting shoulder upon the inner surface of said casing, a strainer of the form of a rotary body in said'casing, an intermediary ringupon said strainer tightly fitting into said shoulder and bearing upon sates the same and dividing the strainer into a lower and upper part, an upper end dlsh of the strainer, a lower end disk of the strainer, an insertion in the upper end disk and a howshaped spring upon said insertion designed also to serve as handle the inlet of the casing being arranged on one side of the said intermediary ring and eccentrieally to the strainer in a manner that the w entering liquid flows tangentially to the strainer the outlet of the easing being arranged on the other side of the said intermediary ring.

In testimony whereof I aifix my signature in presence of two Witnesses.

BRUNO ADLER.
